Nanotechnology helps scientists keep silver shinyThere are thousands of silver artifacts in museum collections around the world, and keeping them shiny is a constant challenge. So scientists are using new technology to give conservators a helping hand. A team of researchers led by Ray Phaneuf, a professor of materials science and engineering at the University of Maryland, College Park, has partnered with The Walters Art Museum in Baltimore to investigate less labor-intensive ways to protect silver artifacts from tarnishing. The new techniques, which might keep silver surfaces shiny for longer than traditional methods, could help ensure that historically important artifacts are preserved for future generations to learn from and enjoy. The researchers will present their work at the AVS 59th International Symposium and Exhibition, held Oct. 28 – Nov. 2, in Tampa, Fla.http://phys.org/news270486214.html

This is the first time that such a structure has been found around a red giant star. It is also the first time that astronomers could get full three-dimensional information about such a spiral. This work is one of the first ALMA early science results to be published.http://phys.org/news269092083.html
Astronomy & SpaceWed, 10 Oct 2012 13:00:25 ESTnews269092083Storage technology developed for fused silica glass to record and read digital data in the order of CD recording densityHitachi today announced the development of technology for the semi-perpetual storage of digital data in fused silica glass which is known for its high resistance to heat and water, in collaboration with the laboratory of Professor MIURA Kiyotaka of the School of Engineering, Kyoto University. The data is recorded using a laser, and can be read using an optical microscope. High recording density was achieved by creating multiple recording layers within the fused silica by changing the focal point of the laser. In the current research, a recording density comparable to that of a compact disc (henceforth, CD) was successfully achieved with 4 layers. http://phys.org/news268555964.html
